Subject[PATCH 0/3] usb: dwc2: fill in gadget caps, configure it for stm32mp15
Date
This patchset fills in 'otg_caps' of the usb_gadget structure, and configures it
on stm32mp15.

When dwc2 is configured as dual role (OTG), the USB gadget descriptors (device mode)
are configured via configfs. This lead in calling usb_otg_descriptor_init().
In usb_otg_descriptor_init() (drivers/usb/gadget/config.c):
- If otg caps structure is provided -> use it
- If otg caps structure isn't provided -> HNP and SRP are enabled by default

This could lead to a configuration mismatch beetween:
- OTG controller: HNP and SRP aren't enabled
- gadget descriptors: HNP and SRP are advertised

Fabrice Gasnier (3):
usb: dwc2: add otg_rev and otg_caps information for gadget driver
usb: dwc2: stm32mp15: set otg_rev
ARM: dts: stm32: set otg-rev on stm32mp151
